The Thomas and Daniel Osborn family papers (81 items) contain correspondence and documents related to the ancestors and descendants of Yale graduate Daniel Osborn of Cutchogue, New York. The materials pertain to family relationships and news, religion, property, and family history, among other subjects.
The bulk of the collection is comprised of correspondence to and between members of the Osborn family, particularly Dr. Thomas Osborn of Riverhead, New York, and his son, minister Thomas Gilbert Osborn of Suffolk County, New York; Connecticut; and New York City. Dr. Thomas Osborn provided his son with family news from Riverhead, New York. Thomas Gilbert Osborn wrote about his experiences at a seminary in New York in 1841 and travel to the Azores in the fall of 1842. Thomas G. Osborn later told his wife Jerusha of his father's failing health and funeral in the summer of 1849. Their letters also refer to finances, local news, and other aspects of everyday life. Thomas G. Osborn's incoming letters from acquaintances frequently pertain to the writers' religious beliefs.
The collection includes several documents and ephemeral items. Three indentures concern Daniel Osborn's acquisition of land from 1737-1739, and 2 certificates pertain to claims registered by Samuel and Chatfield Osborn at a land office in Fort Wayne, Indiana, in 1838. Three medical lecture tickets (1804-1805) and a certificate (August 7, 1806) relate to Dr. Thomas Osborn's medical career, and fragments include an undated item with a lithograph portrait of George Washington surrounded by Civil War-era military paraphernalia and a brief poem.
A notebook contains recipes and instructions for medical treatments and additional notes and accounts, dated as early as 1797 and referring to events as late as 1874. A group of genealogical charts, copied letters, and notes (11 items total) provides information about members of the Fanning, Jagger, and Osborn families from the mid-17th to late 19th century. Two copies of a broadside regard the sale of items from Daniel H. Osborn's estate (March 5, 1867).
